XopD是番茄细菌性斑疹病病原菌euvesicatoria (Xcv)的III型分泌效应物,是病原菌生长和延缓寄主症状发展的必需物质。XopD携带一个c端SUMO蛋白酶结构域,一个决定非特异性dna结合结构域的宿主范围和两个通常在应激诱导转录抑制物中发现的EAR基序。XopD的确切靶点和作用机制尚不清楚。我们报道了XopD直接靶向番茄乙烯应答转录因子SlERF4来抑制乙烯的产生,这是抗xcv免疫和症状发展所必需的。Xcv ΔxopD-induced乙烯产生和乙烯刺激免疫需要SlERF4的表达。XopD与SlERF4在亚核区共定位,并催化SlERF4赖氨酸53的SUMO1水解,导致SlERF4不稳定。赖氨酸53的突变阻止了SlERF4的聚合化,降低了SlERF4的水平,减少了SlERF4的转录。这些数据表明XopD使SlERF4脱氧以抑制抗xcv免疫所需的乙烯诱导转录。
XopD, a type III secretion effector from Xanthomonas euvesicatoria (Xcv), the causal agent of bacterial spot of tomato is required for pathogen growth and delay of host symptom development. XopD carries a C-terminal SUMO protease domain, a host range determining non-specific DNA-binding domain and two EAR motifs typically found in repressors of stress-induced transcription. The precise target(s) and mechanism(s) of XopD are obscure. We report that XopD directly targets the tomato ethylene responsive transcription factor SlERF4 to suppress ethylene production, which is required for anti-Xcv immunity and symptom development. SlERF4 expression was required for Xcv ΔxopD-induced ethylene production and ethylene -stimulated immunity. XopD colocalized with SlERF4 in subnuclear foci and catalyzed SUMO1 hydrolysis from lysine 53 of SlERF4 causing SlERF4 destabilization. Mutation of lysine 53 prevented SlERF4 sumoylation, decreased SlERF4 levels, and reduced SlERF4 transcription. These data suggest that XopD desumoylates SlERF4 to repress ethylene induced-transcription required for anti-Xcv immunity.
